Heat-Timer Varivalve Steam Radiator Valves Quick Vent

The function of the Heat-Timer Varivalve Radiator Air Vent is to provide a means for air to be driven out of Steam Radiators as steam enters. At a given pressure the fill time of a radiator varies proportional to its heat capacity and inversely proportional to the venting capacity of the radiator air vent.

It is possible to control the speed at which a radiator will fill with steam by installing a Heat-Timer Varivalve Radiator Air Vent with a certain venting capacity. Used in this manner, radiator air quick vents are helpful in evening out the heat distribution in a building.
